A wrapper for the POSIX unlink function.
The unlink function deletes a name from the filesystem. If this was the last link to the file and no processes have it
opened, the diskspace occupied by the file is freed.
See your C library manual for more details about unlink. Note that on Windows, it is in general not possible to delete files
that are open to some process, or mapped into memory.
